Pull MFD updates from Lee Jones:
 "New Device Support:
   - Add support for Watchdog to ChromeOS Embedded Controller
   - Add support for GPIOs to ChromeOS Embedded Controller
   - Add supprt for Sound to MediaTek MT6357 CODEC

  New Functionality:
   - Add power-off functionality to Texas Instruments TWL series CODECs

  Fix-ups:
   - Device Tree binding adaptions/conversions/creation
   - Use/convert to new/better APIs/helpers/MACROs instead of
     hand-rolling implementations
   - Trivial; spelling, whitespace, clean-ups, etc
   - Remove superfluous code and simplify overall
   - Fix include lists; alphabetise, remove unused, explicitly add used
   - Use dev_err_probe() to clean-up error paths
   - Convert used cache type over to the Maple Tree in many instances
   - Constify a bunch of static structs
   - Refrain from over-riding resources provided via the firmware

  Bug Fixes:
   - Fix a clock related firmware bug on Dell XPS 9530 et al.
   - Repair incorrect IRQ designations
   - Increase buffer sizes to omit various snprintf compiler errors
   - Ensure errors are handled properly
   - Balance references and prevent resource leaks
   - Rectify Power Key interrupt processing
   - Fix Kconfig related build errors
   - Correct a bunch of register start-up default values"

-* Device tree bindings for Atmel Flexcom (Flexible Serial Communication Unit)
-
-The Atmel Flexcom is just a wrapper which embeds a SPI controller, an I2C
-controller and an USART. Only one function can be used at a time and is chosen
-at boot time according to the device tree.
-
-Required properties:
-- compatible:		Should be "atmel,sama5d2-flexcom"
-			or "microchip,sam9x7-flexcom", "atmel,sama5d2-flexcom"
-- reg:			Should be the offset/length value for Flexcom dedicated
-			I/O registers (without USART, TWI or SPI registers).
-- clocks:		Should be the Flexcom peripheral clock from PMC.
-- #address-cells:	Should be <1>
-- #size-cells:		Should be <1>
-- ranges:		Should be one range for the full I/O register region
-			(including USART, TWI and SPI registers).
-- atmel,flexcom-mode:	Should be one of the following values:
-			- <1> for USART
-			- <2> for SPI
-			- <3> for I2C
-
-Required child:
-A single available child device of type matching the "atmel,flexcom-mode"
-property.
-
-The phandle provided by the clocks property of the child is the same as one for
-the Flexcom parent.
-
-For other properties, please refer to the documentations of the respective
